In order to facilitate the installation of the elastic body 4 into the first slot 12, referring to fig. 4 to 11, at least one side of the first slot 12 penetrates through the sidewall of the first connecting member 1 to form a socket 123 for inserting the elastic body 4. Meanwhile, in order to prevent the elastic body 4 from being pulled out of the insertion port 123 after the elastic body 4 is mounted to the first slot 12, a plug body for restricting the elastic body 4 from being removed from the insertion port 123 is provided in the first slot 12, and the plug body is preferably provided at the insertion port 123. In addition, the side wall of the first slot 12 and/or the surface of the elastic body 4 can be provided with the first salient point, the first salient point generates certain friction force on the movement of the elastic body 4, the elastic body 4 is limited to be displaced in a natural state, and the first salient point plays a role in positioning the elastic body 4. It is understood that the first raised point may be made of an elastic material to facilitate the installation of the elastic body 4 into the first slot 12.

It should be noted that, in embodiment 1 of the present invention, the plug or the first bump is not limited to be disposed in the first slot 12 to achieve the positioning of the elastic body 4 in the first slot 12, and the positioning of the elastic body 4 in the first slot 12 may also be achieved by other solutions, for example, the elastic body 4 is configured to have a diameter-variable structure or the friction of the surface of the elastic body 4 is increased.

Further, in consideration of the installation efficiency and the stability of the connection between the locker 3 and the elastic body 4, embodiment 1 of the present invention locks the locker 3 in the insertion groove 11 by using the tensile pre-load of the elastic body 4. In order to satisfy the requirement that the elastic body 4 forms the stretching pre-tightening force for the locking piece 3, as one embodiment, referring to fig. 3-8, 10-11 and 13, in example 1 of the present invention, the locking piece 3 is provided with a second through hole 31 penetrating through both sides thereof, and the elastic body 4 slides through the second through hole 31.

Wherein, the first slot 12 can be communicated with the inserting groove 11, namely, the elastic body 4 is connected with the part of the locking member 3 inserted into the inserting groove 11; the first slot 12 may not communicate with the insertion groove 11, that is, the elastic body 4 is connected to the locker 3 at a portion not inserted into the insertion groove 11. Referring to fig. 11, in order to improve the stability of the connection of the elastic body 3 and the locker 3, the first slot 12 of the present invention is preferably communicated with the insertion groove 11, and the first slot 12 is provided with a window 121 along one side of the opening of the insertion groove 11, the window 121 being communicated with the opening of the insertion groove 11. The locking piece 3 and the middle part of the elastic body 4 form a whole, and two ends of the elastic body 4 are respectively propped against the inner side wall of the first slotted hole 12. When the middle part of retaining member 3 pulling elastomer 4 was extracted from inserting groove 11, the inside wall of first slotted hole 12 was formed with pressure to the both ends of elastomer 4 for the middle part of elastomer 4 takes place bending deformation, produces tensile pretightning force to retaining member 3, and restriction retaining member 3 directly extracts from inserting groove 11. When the external acting force that acts on retaining member 3 is greater than the tensile pretightning force of elastomer 4, retaining member 3 is pulled out from the opening of inserting groove 11, drives elastomer 4 simultaneously and pulls out from window 121 to make retaining member 3 separate with first connecting piece 1, and then realize the split of first connecting piece 1 and second connecting piece 2.

Referring to fig. 11, in order to observe whether the elastic body 4 passes through the second through hole 31 and improve the fit relationship between the elastic body 4 and the locking member 3, a supporting portion 122 is disposed at a connection portion of the first slot 12 and the insertion slot 11, and the supporting portion 122 is used for supporting the elastic body 4 so that the elastic body 4 partially protrudes from an end surface of the window 121. Further, based on the fact that the elastic body 4 partially protrudes from the end surface of the window 121, when the locking member 3 is inserted into the insertion groove 11, the second through hole 31 partially protrudes from the end surface of the window 121, so that the elastic body 4 can smoothly pass through the second through hole 31, and whether the elastic body 4 passes through the second through hole 31 is observed and judged in the assembling process.

Further, a second protruding point for clamping the elastic body 4 may be disposed on a sidewall of the second through hole 31, so that when the elastic body 4 passes through the second through hole 31, the second protruding point limits the displacement of the elastic body 4, so that the elastic body 4 can stably stay in the second through hole 31.

In order to satisfy the requirement that the elastic body 4 forms a stretching pre-tightening force on the locking member 3, as another embodiment, referring to fig. 14, a second blind hole 32 is formed in a side wall of the locking member 3, an end portion of the elastic body 4 is inserted into the second blind hole 32, and one end of the elastic body 4, which is far away from the locking member 3, abuts against an inner side wall of the first slot 12. When the locking piece 3 pulls one end of the elastic body 4 to be pulled out from the insertion groove 11, the inner side wall of the first slotted hole 12 applies pressure to the other end of the elastic body 4, so that the elastic body 4 is bent and deformed, the locking piece 3 is stretched and pretightened force is generated, and the locking piece 3 is limited to be directly pulled out from the insertion groove 11. When the external acting force acting on the retaining member 3 is greater than the stretching pretightening force of the elastic body 4, one end of the elastic body 4 is separated from the second blind hole 32, so that the retaining member 3 is not pulled out of the insertion groove 11 after the elastic acting force of the elastic body 4, and the elastic body 4 is retained in the first groove hole 12, thereby realizing the separation of the first connecting member 1 and the second connecting member 2.

However, when the locking element 3 is provided with a second blind hole 32, the spring force of the spring body 4 can only act on one side of the locking element 3, which can easily lead to an imbalance of the spring force experienced by the locking element 3 in the insertion groove 11. In order to make the retaining member 3 subject to balanced elastic force to improve stability, referring to fig. 9 and 14, in embodiment 1 of the present invention, two second blind holes 32 are formed on the retaining member 3, and the two second blind holes 32 are disposed axisymmetrically with respect to the retaining member 3; the number of the elastic bodies 4 is two, and the end portions of the two elastic bodies 4 are respectively inserted into the two second blind holes 32. Meanwhile, in order to install the two elastic bodies 4, the two opposite sides of the first slot 12 penetrate through the side wall of the first connecting piece 1 to form two insertion ports 123, the two elastic bodies 4 are installed into the first slot 12 from the two insertion ports 123 respectively, and the end portions of the two elastic bodies are inserted into the two second blind holes 32, so that elastic acting forces are formed on the two opposite sides of the locking piece 3, and the stability of the locking piece 3 in the insertion groove 11 is improved.

To sum up, the connection device of embodiment 1 of the present invention mainly realizes the detachable connection between the first connection member 1 and the second connection member 2 by the following two methods:

(1) When retaining member 3 offered the second through-hole 31 that runs through its both sides, insert retaining member 3 earlier and locate in inserting groove 11, elastomer 4 is installed to first slotted hole 12 in and is slided and pass second through-hole 31 from interface 123, make retaining member 3 and elastomer 4's middle part form a whole, when the external force who acts on retaining member 3 is greater than the elastic force of elastomer 4 to retaining member 3 formation, retaining member 3 and elastomer 4 are pulled out from inserting groove 11's opening direction together, realize the split of first connecting piece 1 and second connecting piece 2. The elastic body 4 can then be removed from the second through hole 31, and the locking member 3 can be inserted into the insertion groove 11, and then the elastic body 4 can be inserted through the second through hole 31 again, so that the connecting device can be recycled.

(2) When second blind hole 32 has been seted up respectively to the both sides of retaining member 3, insert retaining member 3 earlier and locate in inserting groove 11, two elastomers 4 are installed to first slotted hole 12 in and make in two elastomers 4's tip insert two second blind holes 32 respectively from two interface 123 respectively, when the external force who acts on retaining member 3 is greater than the elastic force of elastomer 4 pair retaining member 3 formation, retaining member 3 separates with elastomer 4, make retaining member 3 extract in inserting groove 11, and elastomer 4 remains in first slotted hole 12, realize the split of first connecting piece 1 and second connecting piece 2. Then, the two elastic bodies 4 can be removed from the first slot 12, and then the locking member 3 is inserted into the insertion slot 11, and then the ends of the two elastic bodies 4 are inserted into the two second blind holes 32, so that the connecting device can be recycled.

Example 2

Referring to fig. 15 to 29, in order to detachably connect the first connecting member 1 and the second connecting member 2, the connecting device of embodiment 2 of the present invention further includes a locking member 3 and a bolt member 5; the first connecting piece 1 is provided with a first slotted hole 12 for accommodating the bolt piece 5, the first connecting piece 1 is provided with an inserting groove 11, one end of the locking piece 3 is inserted into the inserting groove 11, the other end of the locking piece 3 is detachably connected with the second connecting piece 2, and the locking piece 3 is provided with a second slotted hole for inserting the bolt piece 5; when the bolt 5 is driven by external force to slide or rotate, the bolt 5 can move out of the second slot hole, so that the locking member 3 can be pulled out of the insertion slot 11.

In this embodiment 2, the specific number of the locking members 3, the inserting grooves 11 and the bolts 5 is not limited. It can be understood that the number of the locking members 3 can be one or more, and the number of the insertion grooves 11 is the same as the number of the locking members 3; the number of bolts 5 can be the same as the number of retaining members 3, and can be greater or less than the number of retaining members 3. The person skilled in the art selects a plurality of locking members 3, insertion grooves 11 and bolts 5 according to the requirements of actual work, so as to control the locking effect between the first connecting member 1 and the second connecting member 2 and the locking effect of the bolts 5 on the locking members 3. Generally, the greater the number of the locking members 3, the stronger the locking effect of the first connecting member 1 and the second connecting member 2; the greater the number of the bolts 5, the stronger the locking effect of the bolts 5 on the locking member 3.

The inserting groove 11 of the embodiment 2 can be located in the middle of the surface of the first connecting member 1, and can also be located at the edge of the surface of the first connecting member 1. The inserting groove 11 is used for limiting the left and right or front and back swing of the locking piece 3 in the horizontal direction, and plays a limiting role.

Wherein, the first slot 12 can be communicated with the inserting groove 11, namely the bolt piece 5 is connected with the part of the locking piece 3 inserted into the inserting groove 11; the first slot 12 may not be in communication with the insertion slot 11, i.e. the bolt 5 is connected to the locking member 3 at a portion not inserted into the insertion slot 11. In order to improve the stability of the connection between the bolt 5 and the retaining member 3, the first slot 12 of the present invention is preferably connected to the insertion slot 11, and the overall structure is more compact and secure, as shown in fig. 17-21.

In order to facilitate the bolt 5 to be installed in the first slot 12, at least one side of the first slot 12 penetrates through a sidewall of the first connecting member 1 to form an insertion opening 123 for inserting the elastic body 4. Meanwhile, after the bolt 5 is mounted in the first slot 12, in order to prevent the bolt 5 from being removed from the insertion port 123, a plug body for limiting the removal of the elastic body 4 from the insertion port 123 is provided in the first slot 12, and the plug body is preferably provided at the insertion port 123.

Based on the structure, after the locking member 3 is inserted into the insertion groove 11, the bolt 5 in the first slot 12 is driven by external force (the external force can be a screwdriver to push the bolt 5) to be inserted into the second slot, the bolt 5 limits the locking member 3 to limit the movement of the locking member 3 relative to the first connecting member 1, so that the locking member 3 is fixed in the insertion groove 11, and the first connecting member 1 and the second connecting member 2 are connected with each other through the locking member 3 and the bolt 5. When the bolt 5 is driven by external force to slide or rotate, the bolt 5 can move out of the second slot, the limiting effect of the bolt 5 on the locking piece 3 is removed, and the locking piece 3 can be pulled out of the insertion groove 11, so that the first connecting piece 1 and the second connecting piece 2 are separated from each other. This embodiment 2 realizes quick installation or split between first connecting piece 1 and the second connecting piece 2 through the relation of being connected of control bolt 5 and retaining member 3, and assembly efficiency is high, has solved current hidden connecting piece structure of domino and troublesome poeration's shortcoming, improves the convenience of hidden piece installation.

The following is a further explanation of a specific structure of the connecting device of embodiment 2 of the present invention. Referring to fig. 16-21, the bolt 5 of this embodiment 2 can be slidably disposed in the first slot 12, so that the bolt 5 can move in the first slot 12 under the driving of external force and control the position relationship between the bolt 5 and the locking member 3.

As a first solution, referring to fig. 18-21 and 34, when the bolt 5 slides in the first slot 12, the second slot of this embodiment 2 is a second through hole 31 penetrating through both sides of the locking member 3, and when one end of the locking member 3 is inserted into the insertion slot 11, the second through hole 31 is located in the insertion slot 11 so that the bolt 5 can pass through the second through hole 31. When the bolt member 5 is driven by external force to pass through the second through hole 31 and stay in the second through hole 31, the bolt member 5 plays a role in limiting and fastening the locking member 3, and the locking member 3 is prevented from being pulled out of the insertion groove 11.

In the above-mentioned solution, when the first connecting member 1 and the second connecting member 2 are in the connected state, in order to avoid the bolt 5 from moving out of the second through hole 31 and ensure the connection stability of the first connecting member 1 and the second connecting member 2, referring to fig. 18 to 19, the inner side wall of the second through hole 31 of the embodiment 2 is provided with a locking point for limiting the sliding of the bolt 5. The clamping point generates a certain friction force on the bolt 5, so that the bolt 5 is limited from abnormal displacement in the second through hole 31, and meanwhile, the clamping point plays a role in positioning the bolt 5. The locking point may be made of an elastic material to increase the friction force of the bolt 5 in the second through hole 31, so as to further prevent the bolt 5 from being removed from the second through hole 31 in abnormal situations.

Referring to fig. 18 to 19, the cross-sectional area of the first slot 12 of this embodiment 2 is larger than that of the second through hole 31. When the first connecting piece 1 and the second connecting piece 2 are disassembled, the bolt piece 5 can be driven to move out of the second through hole 31 into the first slotted hole 12, at the moment, the central axis of the bolt piece 5 positioned in the first slotted hole 12 is lower than that of the second through hole 31, the assembling error is large, the bolt piece 5 is difficult to enter the second through hole 31 again, and misoperation is prevented in the disassembling process.

In addition, in the embodiment 2, the bolt 5 may be provided with a reducing structure, or the surface of the bolt 5 may be provided with a protrusion, or other means for improving the friction of the surface of the bolt 5, so as to prevent the bolt 5 from being removed from the second through hole 31 in a non-detachable state.

As a second alternative, referring to fig. 35, when the bolt 5 slides in the first slot 12, the second slot of this embodiment 2 is a second blind hole 32 disposed on the surface of the locking member 3, and when one end of the locking member 3 is inserted into the insertion slot 11, the second blind hole 32 is located in the insertion slot 11, so that the end of the bolt 5 can be inserted into the second blind hole 32. When the end of the bolt 5 is driven by external force to be inserted into the second blind hole 32, the bolt 5 plays a role in limiting and fastening the locking piece 3, and the locking piece 3 is limited to be pulled out of the insertion groove 11.

In order to improve the balance stability of the locking member 3 when the inserting groove 11 is limited, the number of the second blind holes 32 of the second scheme is two, the second slot holes are arranged in an axial symmetry mode relative to the locking member 3, meanwhile, the number of the bolt pieces 5 is two, and the two second blind holes 32 correspond to the two bolt pieces 5 in a one-to-one mode. Specifically, one of the bolts 5 slides in the first slot 12 and has its end inserted into one of the second blind holes 32, and the other bolt 5 slides in the first slot 12 and has its end inserted into the other second blind hole 32, so that the two bolts 5 respectively form a limiting fastening force on the two opposite sides of the locking member 3, thereby effectively improving the locking effect of the locking member 3 in the insertion slot 11. In order to prevent the end of the bolt 5 from being abnormally removed from the second blind hole 32, a fastening point structure for limiting the sliding of the bolt 5 may be provided on the inner side wall of the second blind hole 32, and the fastening point structure has the same principle and effect as the first solution, and the description thereof is omitted here.

The two schemes do not limit the specific structure of the bolt 5, and the bolt 5 may be a cylinder or a cone, a square column, or other irregular shapes. At the same time, the shape of the first slot 12 and the second slot is adapted to the shape of the bolt 5, so that the bolt 5 can be displaced in the first slot 12 and the second slot.

Further, in the above two solutions, the bolt 5 of this embodiment 2 may have magnetism, that is, the bolt 5 has the property of being attracted by an external magnetic field, the bolt 5 is a permanent magnet made of a magnetic material or coated with a permanent magnet layer or is made of iron, cobalt, nickel, etc. and an alloy thereof, the bolt 5 is driven to move in the first slot 12 by using an external magnet on the surface of the first member 10, which is magnetically attracted to the bolt 5, so as to control the bolt 5 to move out of the second slot, and the limit action of the bolt 5 on the locking member 3 is released, so that the first connecting member 1 and the second connecting member 2 can be detached from each other. Meanwhile, the magnetic force is adopted to drive the bolt piece 5 to displace in the first slot 12, so that the surface of the first component 10 can be prevented from being damaged, the aesthetic property of the first component 10 is ensured, and the integral structure of the connecting device is simplified.

Further, referring to fig. 16-17 and 32, in the case that the bolt 5 is magnetic, the bolt 5 of this embodiment 2 is a cylinder or a cone, and the circumferential outer surface of the bolt 5 is provided with an external thread structure, and the second slot hole is provided with an internal thread knot in matching connection with the bolt 5. The magnetism of the bolt 5 can be specifically that the bolt 5 is provided with a magnetic element, the bolt 5 and the magnetic element can be formed into a whole, and the magnetic element is also fixed on the bolt 5, so that the bolt 5 has magnetism, and the magnetism of the bolt 5 has N pole and S pole at the same time. When the first connecting piece 1 and the second connecting piece 2 are in a connecting state, the external thread structure of the bolt piece 5 is in thread fit with the internal thread structure of the second slotted hole, so that the bolt piece 5 can be effectively prevented from being abnormally moved out of the second slotted hole, and the connecting stability between the first connecting piece 1 and the second connecting piece 2 is ensured. Referring to fig. 37-38, when the bolt 5 needs to be removed from the second slot, the rotating magnet 6 (the rotating magnet 6 also has both N-pole and S-pole) is used to drive the bolt 5 to rotate on the surface of the first member 10, the magnetic interaction between the magnetic property of the rotating magnet 6 and the magnetic property of the bolt 5 causes the bolt 5 to rotate along with the rotating magnet 6, the bolt 5 converts its rotation into linear motion to be removed from the second slot through the threaded fit relationship between the external thread on the bolt 5 and the internal thread of the second slot, and the limit effect of the bolt 5 on the locking member 3 is released, so that the first connecting member 1 and the second connecting member 2 can be detached from each other.

In addition, referring to fig. 32 and 37-38, the end of the plug 5 is provided with a cross-shaped groove or a straight-line-shaped groove or an inner hexagon, so that the plug 5 can be screwed into the second slot hole (the screwing direction can be set to forward rotation) from one end of the socket 123 by using an external tool such as a screwdriver during installation, and the operation is more concise and effective.

Further, referring to fig. 22-25 and 36, in the case that the bolt 5 is magnetic, one end of the bolt 5 of this embodiment 2 is conical, the outer circumferential surface of the bolt 5 is provided with an external thread structure, the bolt 5 is slidably disposed in the first slot 12, and the second slot is a tapered hole 35 disposed on the surface of the locking member 3. The number of the tapered holes 35 may be one or more, which is adapted to the number of the bolts 5. The fact that the bolt 5 has magnetic properties is understood to mean that: referring to fig. 24-25, the bolt 5 as a whole may be made of a magnetic material; referring to fig. 22-23, the plug 5 may be formed of two parts, a first part having a cone 54 and an external thread structure, and the first part may be made of a non-magnetic material such as plastic or metal, preferably stainless steel, with high corrosion resistance and long service life; the second part is of magnetic material and forms an integral structure with the first part, so that the bolt 5 is entirely magnetic.

Meanwhile, the end face of the end of the bolt piece 5 far away from the cone shape is provided with a cross-shaped groove or a straight-shaped groove or an inner hexagon. When the bolt 5 is connected with the locking member 3, an external tool such as a screwdriver is used for acting on the cross-shaped groove or the straight-line-shaped (or inner hexagonal) groove to drive the bolt 5 to slide and rotate (the rotation direction can be set to be positive rotation), so that one end of the bolt 5 with the cone 54 structure can extend into the tapered hole 35, the bolt 5 is screwed into the locking member 3 in a self-tapping positive direction, the matching precision is higher, and the connection between the bolt 5 and the locking member 3 is tighter and firmer.

Further, referring to fig. 24-25, the cross-sectional area of the first slot 12 is greater than the cross-sectional area of the stud 5. When the first connecting part 1 and the second connecting part 2 are detached, the bolt 5 is driven to rotate by the rotating magnet 6 on the surface of the first member (at this time, the rotation direction is reversed), the bolt 5 is reversely screwed out from the tapered hole 35, so that the bolt 5 is separated from the locking part 3, and then the bolt 5 is moved out from the tapered hole 35 into the first slot 12, at this time, the bolt 5 falls on the inner bottom in the first slot 12, so that the central axis of the bolt 5 in the first slot 12 is lower than that of the tapered hole 35, the assembly error is large, the bolt 55 is difficult to enter the tapered hole 35 again (the bolt 55 is screwed in forward direction) under the driving of the rotating magnet, and the operation error in the detaching process is prevented.

Further, with reference to fig. 26-27, the bolt 5 is slidingly arranged in a first slot 12, the second slot being a tapered hole 35 arranged in the surface of the retaining member; the bolt piece 5 comprises a first self-tapping block 53 and a first power block 54 with magnetism; the magnetic properties of the first power block 54 have both an N-pole and an S-pole such that the first power block 54 can be driven to rotate using a rotating magnet on the exterior of the first member. One end of the first self-tapping block 53 is in a cone shape, the other end of the first self-tapping block 53 is provided with a first extending arm 531, and the outer circumferential surface of the first self-tapping block 53 is provided with an external thread structure; one end of the first power block 54 is provided with a second extending arm 541, and the other end of the first power block 54 is provided with a first connecting part which is a cross-shaped groove or a straight-shaped groove or an inner hexagon; the number of the first protrusion arm 531 and the second protrusion arm 541 may be one or two, and the first protrusion arm 531 is connected to the second protrusion arm 541. When an external tool such as a screwdriver is connected to the first connection portion to drive the first power block 54 to rotate (the rotation direction can be set to be positive rotation) and slide in the first slot 12, the first self-tapping block 53 and the first power block 54 can be driven to rotate synchronously, and one end of the first self-tapping block 53 in a cone shape can be inserted into the tapered hole 35, and then the locking member can be screwed into the locking member in a self-tapping positive direction. When the first connecting member 1 is separated from the second connecting member 2, the first power block 54 is driven to rotate (the rotation direction is reversed) by the rotating magnet on the surface of the first member, so as to drive the first self-tapping block 53 to reversely unscrew from the tapered hole 35, so that the bolt 5 is separated from the locking member, and the bolt 5 is moved out of the tapered hole 35 into the first slot 12.

Preferably, referring to fig. 27, the cross-sectional area of the first slot hole 12 is larger than the cross-sectional area of the first self-tapping block 53. That is, after the first self-tapping block 53 is screwed out from the tapered hole 35 in the reverse direction, the first self-tapping block 53 falls on the inner bottom of the first slot 12, so that the central axis of the first self-tapping block 53 located in the first slot 12 is lower than the central axis of the tapered hole 35, the assembly error is large, the first self-tapping block 53 is difficult to enter the tapered hole 35 again under the driving of a rotating magnet (the first self-tapping block 53 is screwed in the forward direction), and misoperation in the disassembling process is prevented.

One end of the second self-tapping block 55 is in a cone shape, the other end of the second self-tapping block 55 is connected with the connecting block 56 in a clamping manner (a connection manner of concave-convex matching is available), and the outer circumferential surface of the second self-tapping block 55 is provided with an external thread structure; connecting block 56 is connected with second power block 57 through spring 58 at one end back to connecting block 56, and second power block 57 is provided with a second connecting part at one end far away from spring 58; the second connecting part is a cross-shaped groove or a straight-line-shaped groove or an inner hexagon. When an external tool such as a screwdriver is connected to the second connecting portion, the second power block 57 is driven to rotate (the rotation direction can be set to be positive rotation) and slide in the first slot 12 and is fixed at a specific position; the second self-tapping block 55 is driven to rotate through the connecting block 56, one end of the second self-tapping block 55 in a cone shape can be inserted into the tapered hole 35, then the second self-tapping type positive screwing-in locking piece is screwed in, in the screwing-in process, in the releasing process of the compression deformation energy of the spring 58, an extra thrust can be generated on the second self-tapping block 55 by utilizing the compression deformation energy of the spring 58, so that the second self-tapping block 55 is tightly connected with the connecting block 56 in the positive moving process of the connecting block 56, and the second self-tapping block 55 cannot be separated from the connecting block 56. When the first connecting member 1 is detached from the second connecting member 2, the rotating magnet on the surface of the first member rotates the connecting block 56 (the rotation direction is reversed) to rotate the second self-tapping block 55 out of the tapered hole 35 in the opposite direction, so that the bolt 5 is separated from the locking member, and the bolt 5 is moved out of the tapered hole 35 into the first slot 12.

Preferably, the cross-sectional area of the first slot hole 12 is larger than the cross-sectional area of the second self-tapping block 55. That is, after the second self-tapping block 55 is screwed out from the tapered hole 35 in the reverse direction, the second self-tapping block 55 falls on the bottom of the inner side of the first slot 12, so that the central axis of the second self-tapping block 55 in the first slot 12 is lower than the central axis of the tapered hole 35, the assembly error is large, the second self-tapping block 55 is difficult to enter the tapered hole 35 again under the driving of a rotating magnet (the second self-tapping block 55 is screwed in the forward direction), and misoperation in the disassembly process is prevented.

Further, the peg 5 may be non-magnetic.

It is understood that the locking member 3 and the first connecting member 1 may be integrated by injection molding or by gluing, and is not limited thereto.

Example 4

This embodiment 4 discloses a locking structure for achieving the purpose of locking the locking member 3 and the second connecting member 2 to each other in the above embodiments 1 to 3.

Referring to fig. 3-9, 12-14, 31, 33-36, and 41-44, the locking structure of embodiment 4 of the present invention includes a through channel 21 for the locking member 3 to pass through is formed on the second connecting member 2, a first tooth portion 211 is formed on an inner sidewall of the through channel 21, and the locking member 3 is provided with a second tooth portion 33; the first tooth part 211 is provided with a plurality of first tooth bodies which are sequentially arranged at intervals along the axial direction of the penetration passage 21, and the second tooth part 33 is provided with a plurality of second tooth bodies which are sequentially arranged at intervals; the locking piece 3 is inserted into the through channel 21 along a predetermined direction, and the first tooth bodies are respectively engaged with the second tooth bodies to limit the locking piece 3 from moving towards the opposite side of the predetermined direction.

Referring to fig. 12-14 and 33-36, the first tooth body and the second tooth body are both in the form of helical teeth, and each of the first tooth body and the second tooth body includes a horizontal surface and an inclined surface, when the first tooth body and the second tooth body are engaged, a tooth-type ratchet mechanism is formed, so that the second tooth body can move along a predetermined direction, the first tooth body abuts against the second tooth body to limit the first tooth body from moving to the opposite side of the predetermined direction, and the locking member 3 and the second connecting member 2 are limited from being separated relatively, so that the locking member 3 and the second connecting member 2 are locked with each other. And the locking member 3 can be separated from the second coupling member 2 after passing through the through passage 21 in a predetermined direction, so that the locking member 3 and the second coupling member 2 can be disassembled from each other in the

above embodiments

1 and 2.

Further, in order to improve the locking effect between the locking member 3 and the second connecting member 2, the number of the first teeth 211 and the second teeth 33 of embodiment 4 of the present invention is at least two, and the first teeth of each group of the first teeth 211 and the second teeth of each group of the second teeth 33 are engaged with each other to achieve the purpose of locking, and at the same time, the locking stability is effectively improved.

When retaining member 3 inserts and locates in cross-under passage 21, there is the removal clearance within the error allowed range in arbitrary one first tooth between two second tooth for first tooth or second tooth can take place small displacement on removing the clearance, thereby lead to retaining member 3 can shake on second connecting piece 2, and locking effect is relatively poor. Referring to fig. 41 to 44, in order to improve the locking effect between the locking member 3 and the second connecting member 2, the first tooth bodies of at least two sets of first tooth portions 211 are distributed along the axial direction of the penetrating channel 21 in a staggered manner, and the second tooth bodies of each set of second tooth portions 33 are located on the same horizontal plane along the axial direction of the penetrating channel 21, so that the positions of the first tooth bodies of at least two sets of first tooth portions 211 in the movement gap are different, and the movement gap between the first tooth bodies of at least one set of first tooth portions 211 and the two second tooth bodies can be reduced by forming relative constraint through relative dislocation between the first tooth bodies of at least two sets of first tooth portions 211, so that the first tooth bodies of one set of first tooth portions 211 are engaged with the second tooth bodies more tightly, thereby greatly improving the locking effect between the locking member 3 and the second connecting member 2.

Specifically, when the first tooth bodies between the two sets of first tooth parts 211 are distributed in a staggered manner along the axial direction of the cross-connecting channel 21, the moving clearance of the first tooth bodies between the two second tooth bodies is effectively reduced by one half, and the locking effect between the locking member 3 and the second connecting member 2 is improved. When the first tooth bodies among the three groups of first tooth bodies 211 are distributed in a staggered manner along the axial direction of the cross-connecting channel 21, one third of the moving gap of the first tooth bodies between two second tooth bodies is effectively reduced, and the locking effect between the locking piece 3 and the second connecting piece 2 is improved. By analogy, when the number of the groups of the first teeth bodies staggered with each other among the multiple groups of the first teeth bodies is larger, the moving gap of the first teeth bodies between the two second teeth bodies is smaller, so that the locking effect of the locking member 3 and the second connecting member 2 is better.

In the same principle, in the embodiment 4 of the present invention, the second tooth bodies of at least two sets of the second teeth 33 are distributed in a staggered manner along the axial direction of the through-connection channel 21, and the first tooth bodies of each set of the first teeth 211 are located on the same horizontal plane along the axial direction of the through-connection channel 21, so as to achieve the effect of improving the locking effect of the locking member 3 and the second connecting member 2.

In the case of satisfying the above-mentioned requirement for improving the locking effect between the locking member 3 and the second connecting member 2, in order to facilitate the manufacturing and improve the assembly efficiency, referring to fig. 41 and 43, the number of the first teeth 211 is two, the number of the second teeth 33 is two, and the two sets of the first teeth 211 and the two sets of the second teeth 33 are in one-to-one correspondence; the two sets of second teeth 33 are arranged axisymmetrically with respect to the retaining member 3. The two sets of first teeth 211 and the two sets of second teeth 33 are in one-to-one correspondence, which means that the orientations are matched, so that one set of first teeth 211 is meshed with one set of second teeth 33, and the other set of first teeth 211 is meshed with the other set of second teeth 33. The two sets of second teeth 33 are arranged on the locking member 3 in an axisymmetric manner, so that the orientation of the second teeth 33 of the locking member 3 is not required to be distinguished during assembly, and the locking member 3 can be inserted into the through-connection channel 21 in both the forward and reverse directions.

With reference to fig. 41 and 43, in order to further facilitate the insertion of retaining member 3 into passage 21, retaining member 3 is provided with a first inclined portion 34 at one end of passage 21, and a second inclined portion 212 guided in cooperation with first inclined portion 34 is provided on the side wall of inlet 213 of passage 21. Wherein the surface of the first inclined portion 34 and the surface of the second inclined portion 212 are fitted to each other, facilitating stable insertion of the locker 3 into the penetration passage 21 in a predetermined direction.

Further, referring to fig. 17 to 29, in order to prevent the resistance of the bolt 5 of the above embodiment 2 in the second slot from being larger than the external driving means (external magnet or rotating magnet 6) so that the bolt 5 cannot be removed from the second slot, and referring to fig. 40, in order to realize the above embodiment 3 by breaking the second connecting member to separate the locker from the second connecting member, the second connecting member 2 of the embodiment 4 is provided with an insertion slot 28 on the end surface of the outlet 214 end of the through-passage 21, and by forcibly opening after inserting the expanding member into the insertion slot 28, the through-passage 21 is broken so that the first tooth and the second tooth cannot be normally engaged, and the second connecting member 2 and the locker 3 can be relatively separated so that the first connecting member 1 and the second connecting member 2 can be separated.

Further, in order to ensure that the locking member 3 only bears the acting force along the axial direction of the threading channel 21, the structure of the locking member 3 is matched with that of the threading channel 21, and the surface of the locking member 3 is attached to the inner side wall of the threading channel 21, so that the inner side wall of the threading channel 21 limits the radial movement of the locking member 3, and the locking effect of the locking member 3 and the second connecting member 2 is improved. In order to improve the locking effect of the locking member 3 in the through-passage 21, referring to fig. 12 and 33, the cross section of the locking member 3 of embodiment 4 of the present invention is square, which effectively limits the radial movement of the locking member 3 in the through-passage 21.

Example 5

Embodiment 5 of the present invention discloses a fixing structure for clamping the first connecting member 1 and the second connecting member 2 of embodiments 1-3 in the first arc-shaped groove 101 and the second arc-shaped groove 201.

The following is a specific description of the fixing structure of the present embodiment 5 applied to the first connecting member 1 and the first member 10.

Referring to fig. 1-2 and 45-52, the surface 16 of the first connecting member is provided with a first elastic fixing portion 17, and when the first connecting member 1 slides in along the bottom wall 101c of the first arc-shaped groove, the first elastic fixing portion 17 is elastically deformed and abuts against the inner side wall 101b of the first arc-shaped groove to limit the relative movement between the first connecting member 1 and the first member 10. Further, according to the actual working requirement, one or more first elastic fixing portions 17 are provided on the surface 16 of the first connecting member to enhance the clamping effect of the first connecting member 1 in the first arc-shaped slot 101. Preferably, the number of the first elastic fixing portions 17 in embodiment 5 of the present invention is two, and the two first elastic fixing portions 17 are respectively disposed on the two opposite surfaces 16 of the first connecting member, so that the two opposite surfaces 16 of the first connecting member 1 respectively abut against the inner side wall 101b of the first arc-shaped groove, thereby improving the clamping effect and stability of the first connecting member 1 in the first arc-shaped groove 101.

Further, referring to fig. 1-2, since the first arc-shaped groove 101 has shallow ends and deep middle, the contact area between the two ends of the surface 16 of the first connecting member and the two ends of the inner side wall 101b of the first arc-shaped groove is smaller, and the contact area between the central area of the surface 16 of the first connecting member and the central area of the inner side wall 101b of the first arc-shaped groove is larger, in order to improve the clamping effect of the first connecting member 1 in the first arc-shaped groove 101, the elastic deformation amount of the central area of the first elastic fixing portion 17 is larger than the elastic deformation amount of the two ends of the first elastic fixing portion 17, so that the elastic pre-tightening force at the position where the contact area between the first connecting member 1 and the first arc-shaped groove 101 is larger, and the first connecting member 1 is further firmly clamped in the first arc-shaped groove 101. Meanwhile, the smaller elastic deformation amount at the two ends of the first elastic fixing portion 17 is beneficial to the first connecting piece 1 to slide into the first arc-shaped groove 101, so that the phenomenon that the first connecting piece 1 needs large external force to push the first connecting piece 1 to slide in due to overlarge friction force of the whole first connecting piece 1 is avoided, and the device is labor-saving and convenient.

Reference is made to fig. 45 to 47, 49 to 51, which are a specific structure of the first elastic fixing portion 17 according to embodiment 5 of the present invention. The first elastic fixing portion 17 includes a first arc positioning portion 171 provided on the surface 16 of the first connecting member, and a first elastic member 172 provided on the first arc positioning portion 171; the first elastic member 172 can elastically deform and abut against the bottom of the inner sidewall 101b of the first arc-shaped groove. Correspondingly, referring to fig. 1-2, the bottoms of the two inner side walls 101b of the first arc-shaped groove are respectively concavely provided with a first arc-shaped mounting groove capable of accommodating the first arc-shaped positioning portion 171, and the first arc-shaped mounting groove extends to the opening of the first arc-shaped groove 101 along the extending direction of the bottom wall 101c of the first arc-shaped groove, so that two ends of the opening of the first arc-shaped groove 101 are formed with T-shaped notches 101d. When the first connecting member 1 slides in along the bottom wall 101c of the first arc-shaped groove, the first arc-shaped positioning portion 171 slides in the first arc-shaped mounting groove from the notch 101c, and the surface 16 of the first connecting member is attached to the inner side wall 101b of the first arc-shaped groove. After the installation is finished, the first elastic component 172 is elastically deformed and abuts against the bottom of the inner side wall 101b of the first arc-shaped groove, so that the first arc-shaped positioning portion 171 has a large abutting force between the bottoms of the inner side walls 101b of the first arc-shaped groove, a large pre-tightening force is formed between the first connecting piece 1 and the first member 10, and the first connecting piece 1 and the first member 10 are further limited from moving relatively. Meanwhile, in order to ensure that the arc-shaped edge of the first arc-shaped positioning portion 171 can be attached to the bottom wall 101c of the first arc-shaped groove, the radius of the arc-shaped edge of the first arc-shaped positioning portion is larger than that of the bottom wall 101c of the first arc-shaped groove, so that after the installation is finished, the arc-shaped edge of the first arc-shaped positioning portion 171 can be attached to the edge of the bottom wall 101c of the first arc-shaped groove, the first arc-shaped positioning portion 171 is ensured to be located at the bottom of the inner side wall 101b of the first arc-shaped groove, and then a large pre-tightening force is generated between the first elastic part 172 and the bottom of the inner side wall 101b of the first arc-shaped groove, and the clamping effect between the first connecting part 1 and the first component 10 is improved.

The first elastic member 172 is made of a material that can recover to its original shape after an external force is removed, for example, a polymer material such as rubber or silica gel, so that when the first connecting member 1 slides into the first arc-shaped groove 101 under the action of the external force, the first elastic member 172 is compressed and deformed, and when the external force is removed, the elastic pre-tightening force of the first elastic member 172 abuts against the bottom of the inner sidewall 101b of the first arc-shaped groove, so that the first arc-shaped positioning portion 171 has a large abutting force between the bottoms of the inner sidewalls 101b of the first arc-shaped groove, the friction coefficient between the first connecting member 1 and the inner sidewall 101b of the first arc-shaped groove is increased, and the purpose of limiting the relative movement between the first connecting member 1 and the first member 10 is achieved.

The first elastic member 172 may have a continuous rib structure or a protrusion structure disposed at intervals, and the following description will be made when the first elastic member 172 has a rib structure or a protrusion structure.

Referring to fig. 45 and 49, the first elastic member 172 is an arc-shaped convex strip disposed along the arc-shaped edge of the first arc-shaped positioning portion 171. The continuous arc-shaped raised line structure can increase the contact area with the inner side wall 101b of the first arc-shaped groove, so that the friction force between the first connecting piece 1 and the first arc-shaped groove 101 is larger, and the clamping effect of the first connecting piece 1 on the first arc-shaped groove 101 is improved.

Referring to fig. 46-47, 50-51, the first resilient member 172 is a resilient protrusion. When the first elastic component 172 is an elastic protrusion, in order to ensure that the first elastic component 172 provides sufficient elastic pretightening force, the number of the elastic protrusions is multiple, the elastic protrusions are arranged at intervals along the direction of the arc edge of the first arc positioning portion 171, and the distance between any two adjacent elastic protrusions can be the same or different, so that the first elastic fixing portion 17 forms uniform and balanced pretightening force on the first member 10, and the clamping effect of the first connecting piece 1 in the first arc groove 101 is improved.

Further, referring to fig. 49 and 53, the elastic protrusion is arc-shaped, and the elastic protrusion extends along the direction of the arc-shaped edge of the first arc-shaped positioning portion 171 to ensure the elastic pre-tightening force between the elastic protrusion and the first arc-shaped groove 101. Further, if the first member 10 is made of cork or other elastic materials, when the first connecting member 1 is accommodated in the first arc-shaped groove 101, the inner sidewall 101b of the first arc-shaped groove can be elastically deformed to improve the friction between the first connecting member 1 and the inner sidewall 101b of the first arc-shaped groove, so that the elastic force of the elastic protrusion can be reduced, or the elastic force of the elastic protrusion can be smaller than the elastic force of the first member 10. Furthermore, the elastic protrusions are provided with the spherical balls capable of rolling, and the arrangement of the spherical balls further avoids the situation that the first connecting piece 1 needs large external force to push the first connecting piece 1 to slide in due to overlarge friction force of the whole first connecting piece 1, and is labor-saving and convenient.

In some embodiments, the material of the first arc-shaped positioning portion 171 is the same as the material of the first connecting member 1, such as a thermosetting plastic material, the first arc-shaped positioning portion 171 and the first connecting member 1 can be formed by injection molding as a single piece, and the first elastic member 172 is glued or otherwise disposed on the first arc-shaped positioning portion 171. In other embodiments, the first arc-shaped positioning portion 171 and the first elastic member 172 are made of the same material as that of the first connecting member 1, and the first arc-shaped positioning portion 171, the first elastic member 172 and the first connecting member 1 are formed as a single piece by injection molding, so that the structure is firmer.

Reference is made to fig. 48 and 52, which are another specific structure of the first elastic fixing portion 17 in embodiment 5 of the present invention. The first elastic fixing portion 17 is an elastic protruding strip in a wavy shape. The elastic protruding strips extend along the direction of the arc-shaped edge of the first connecting piece 1, so that the contact area between the elastic protruding strips and the inner side wall 101b of the first arc-shaped groove is increased, and the first connecting piece 1 is firmly clamped in the first arc-shaped groove 101. Meanwhile, when the elastic convex strip in the irregular shape is elastically deformed, the contact area between the elastic convex strip and the first arc-shaped groove 101 is larger, so that the pretightening force of the first connecting piece 1 in the first arc-shaped groove 101 is larger, and the first connecting piece 1 can be firmly clamped in the first arc-shaped groove 101. The first, undulating, elastic anchoring portion 17 may be formed in one piece with the first connecting element 1, and may also be fixed to the surface 16 of the first connecting element by gluing or other means.

In addition, the fixing structure of this embodiment 5 is applied to the second connecting member 2 and the second member 20, and the structure and principle of the fixing structure applied to the first connecting member 1 and the first member 10 are the same, referring to fig. 22-25, that is, the surface 26 of the second connecting member is provided with the second elastic fixing portion 27, when the second connecting member 2 slides in along the arc surface of the second arc-shaped groove 201, the second elastic fixing portion 27 is elastically deformed and tightly abuts against the inner side wall 201b of the second arc-shaped groove, so as to limit the relative movement between the second connecting member 2 and the second member 20. Therefore, the detailed structure of the second elastic fixing portion 27 is omitted in this embodiment 5, and those skilled in the art can determine the structure of the second elastic fixing portion 27 by referring to the detailed structure of the first elastic fixing portion 17 on the first connecting member 1.

In some embodiments, the clamping effect can be realized by the way of interference fit between the fixture block 13 and the clamping groove 23, and also can be realized by the way of increasing the friction force through the elastic deformation of the fixture block 13, so that the embodiment 6 does not limit the specific structure or the clamping principle of the fixture block 13 and the clamping groove 23. The engaging block 13 can be a hemisphere or a cube, so that the embodiment 6 does not limit the specific structure of the engaging block 13.

Illustratively, the number of the clamping blocks 13 on the first connecting member 1 is two, the number of the clamping grooves 23 on the second connecting member 2 is also two, the shapes of the clamping blocks 13 are matched with the shapes of the clamping grooves 23, and the cross-sectional areas of the clamping blocks 13 are slightly larger than the cross-sectional areas of the clamping grooves 23, so that the two clamping blocks 13 are clamped in the two clamping grooves 23 respectively in an interference fit manner, and further the clamping effect of the first connecting member 1 and the second connecting member 2 is improved.

Illustratively, the number of the elastic plates 14 on the first connecting member 1 is two, and the bending directions of the two elastic plates 14 are opposite, so that the two elastic plates 14 are axisymmetrical with respect to the first connecting member 1, and correspondingly, the number of the receiving grooves 24 is two, and the two elastic plates 14 are respectively snapped in the two receiving grooves 24 to improve the clamping effect of the first connecting member 1 and the second connecting member 2.
